Reviews of TEC1-12706 Thermoelectric Peltier Cooler 12 Volt 92 Watt

Customer Ratings:

This replacement arrived with no damage to the ceramic exterior of the device. The edges along the square perimeter were properly sealed to prevent moisture from shortening the life of the device. Since the 12vdc device had no markings on either side as to which side is the cold or hot side, I had to hook the peltier device up to a 5vdc power supply. The red lead was connected to +5vdc and the black lead was connected to common / ground. Power was applied for only 3 seconds and quickly shut off. That short time was enough to sense with my fingers which side is the cool side and which side was the hot and side and without damaging the device from heat. Do not run this device with a power supply more than a few seconds without a heatsink mounted to the device! You will destroy the device, if you do.

After having found the cool side, I marked it with a sharpie. The defective moisture damaged device in the B&D refrigerator was removed and all of the old heatsink compound was scrapped off of the heatsinks. The new peltier device was mounted with the cool side towards its cool side heatsink and the same was done for the hot side (larger) heatsink using a modest amount of Arctic 5 Silver heatsink compound. The leads were connected up by color to the power supply, red to positive (+) and black to negative (i.e. common, "-" or ground) using butt splices. The B&D refrigerator was plugged in and allowed to run with the thermostat set to the coldest setting. The first couple of days, the temperature was 47 degrees. However, after the break in period of the Arctic 5 Silver compound, the refrigerator runs at 42 degrees at a control setting just above the lowest cooling setting (i.e. at nearly the warmest setting or the lowest power usage setting). Efficiency, and the temperatures, would be improved, if I had replaced the other device, which will soon be done.

New unit works just fine. The new device is the exact replacement for the one that had failed within my 12 bottle wine cooler.

Bought the cooler to replace one that failed in a wine fridge. Works great. Arrived early. Would recommend.

Buy Delonghi TCH7590ER - Ceramic Fan Heater with Remote Control

Customer Ratings:

I got this product because I live in an attic space and need the extra heat in the winter at night. Well, first of all this thing is loud. If you're a light sleeper, don't get this. Second, if you even scoot it along the floor (not even tilting it but just scooting), it shuts off. Every time the heat goes on or off depending on the thermostat, there's a loud beep. If you scoot it, there's a loud beep. If you do anything to it there is a loud beep. This heater is very annoying and I will soon be replacing it.

When my old Lasko heater died (the one whose remote control button function locations did not match the same function locations on the similar-shaped control panel on the unit a stupid design error), I looked for a different brand model heater that came with a remote control.

I thought I had found a reasonable substitute in this model, until I set it up and ran through the functions on the remote control, supposedly "the same functions as included on the control panel".

Guess what highly useful feature that I use frequently when I wish to adjust my heater before falling asleep withOUT getting out of bed got left OFF the remote control that comes with this machine:

THE TIMER.

THERE IS NO TIMER SETTING ON THE REMOTE CONTROL.

Whatever other features this machine has that might be nice, this machine is functionally useless to me, and I must return it.

Temperature sensor was bad on my heater...intermittently. This happen a couple of months after the purchase and Delonghi would not respond to my email.

Currently, the heater is broken (1.5 year old). The heater automatically turns off after a couple of minutes, in which it does not put out any heat during those few minutes. I'm shopping for a new heater now...hopefully the Lasko doesn't fail me.

Definitely works better in large rooms! One annoyance is if you some much as gently pick it up, it resets itself. Other than that, it's a phenomenal heater!

(caveat-I have only used this heater for 1 day)

Pros: small/easily placed, quiet fan, rotation (can be turned off), effective heat (at least for small space (area around a desk chair); I have not tried a large space), low price (I paid $40 from J&R)

Cons: high-pitched loud beep that sounds every time you change anything, including upon turning on and turning off, fan has only medium and high settings, no low setting

If you want a thermostat-controlled fan space heater then this is good for the price. If you want something with adjustable heat, this is not it. Heat is either on or off, depending on the temperature you set and the temperature that the heater's thermostat measures. If you want a little extra heat where you are sitting (e.g. chilly office), this is NOT a good solution because instead of providing a steady, low supply of heat that you can adjust according to your environment, the heater will just keep turning on and off according to the temperature setting. Every on and off is accompanied by a loud beep not really appropriate in an office.

If I had known that every change in setting and every on and off would be accompanied by a loud beep, I would not have bought this product.

This space heater apparently also acts as a space cooler-you might want to confirm that.

I use this thermostat to turn on and off an attic fan when temperatures get too high. I've found that every few months mine needs to be turned off and reset, or the fan will just run continously. This is no big deal for my purposes, but if you use it for applications where temperature control is critical for keeping animals or plants alive, check it periodically or buy a more expensive unit.

I recently purchased two of these units to regulate the temperature in my bedroom and my living room. I live in a 1 bedroom apartment. The temperature readout is spot on and it's easy to program. However I do have two complaints:

1. The unit can only program weekdays and weekends. That means you can't choose a specific day of the week to program. For example, I am never at my apartment on Saturdays, however since Saturday and Sunday must have the same schedule, as well as monday-friday, I'm wasting energy.

2. In order for this unit to work, there MUST be a ground plugged into the outlet. I bought two "DeLonghi HHP1500 Mica Panel Radiator" heaters (they are amazing, I highly recommend) which don't have a ground. In order for it to work, I had to plug in an extension cord into the thermostat to trick it into thinking the ground was plugged in, then I plugged my heater into the extension cord and it worked.

Overall, I recommend the thermostat.

I bought this for use in my garage workshop, to control a small gas wall furnace/space heater. The heater has its own thermostat, but it's not programmable and it's terribly inaccurate, prone to wide fluxuations in temperature. This device does a lovely job of keeping the shop comfortable when I expect to be there while letting the place cool off at night to save energy. It's lovely, and such a simple idea that I wonder who no other thermostat manufacturer seems to offer an equivalent product.

Honest reviews on Lux WIN100 Heating & Cooling Programmable Outlet Thermostat

The LUX WIN100 Heating & Cooling Programmable Outlet Thermostat is the perfect solution for heating or cooling one room. I purchased three (3) units: one for each bedroom hooked up to a small oil-filled radiator to heat the bedrooms in the winter. I don't like forced air heating because it dries out the air too much. This has not only allowed us to breath comfortably at night, but also cut my electric bill. Although we broke record lows this fall (avg of 30-40 degrees every night for the month of November), my electric bill was the no higher than an avg November. I was expecting a $200-$300 electric bill and it was only $150 for Nov. Not bad for an all-electric three bedroom home.

With the ability to program the temp for each day (four time settings for M-F, and four times for S-S) The Lux WIN100 Heating & Cooling Programmable Outlet Thermostat takes all the work out of remembering to turn on or off the heat (or air). For example, you could set the thermostat to 68 degrees at 9PM, 65 at 3AM, 72 at 6AM, and 60 at 8AM. This could be the M-F setting. You could set the temp for four different times for S-S as well.

Another nice feature is the ability to program the unit without having to be plugged in (armchair programming) thanks to the backup batteries, included. They are of the button cell type, and are supposed to be replaced every year, but I think I will just wait until they die. And last but not least is the "hold" button, which allows you to manually adjust the temp and keep it there, thus overriding the programmed temp settings. It will stay at that temp until you press hold again, thereafter returning to the programmed setting.

The thermostat is rated at 120VAC, 15A -enough power to run most space heaters or A/C units. The unit will operate manually operated heaters (not digital) and manual or digital A/C units if the digital A/C unit has auto on capability after power failure. The thermostat works by cutting the power to the heater/AC unit once the desired temp has been reached.

Thanks, Lux, for a great product!

I installed 2 of these in bedrooms and plugged in electric heaters. They maintain the room temperature +1 degree even though I lower the central heating temperature to save money. Previously I used the thermostats built into Delongi oil filled electric radiators to control the room temperature. The best I could get was maybe +3 degrees. The WIN100 completely solved the temperature stability and targeting problems I was having!

The thermocouple and electronic thermostat in the WIN100 is much more accurate than the built in bi-metalic mechanical thermostats in most portable electric heaters. The bi-metalic thermostats had a scale of 1-6 and I had to set each heater to a different number to get the right room temperature. Also I had to bump the set point up and down depending on how cold it was outside. Probably something to do with varying thermal gradient inside the heater housing... anyway, inherent problem when the temperature sensor is next to the heater.

After installing the WIN100, the room temperature was completely stable!

Programming is straight forward. Typical for an electronic thermostat.

Heater set up suggestions:

1) Use oil filled radiator heaters for bedrooms. They are SAFE, QUIET and don't make drafts.

2) Set your heater for medium power, not high. Long, low heat input keeps the room temperature more stable. Lower power reduces the chance of overheating and fire if you have a slightly damaged wall receptacle. (If your receptacle is very warm to the touch, replace it with a new spec grade receptacle.)

3) Place the WIN100 on an outside wall. This is opposite what the user manual says, but it will give you a more stable room temperature. The apparent temperature for a person is a function of the air temperature (conduction & convection heating) and the wall temperature (thermal radiation heating). When it is really cold outside, the walls get colder and you need to bump up the air temperature to keep the room "feeling" the same temperature. Putting the temperature sensor on the cold wall gives you an automatic bump in air temperature as needed.

4) Put the heater away from the WIN100 temperature sensor. Put your hand by the WIN100. If you can feel the heat of the heater, it is too close.

5) Put the heater under a window. That's where most of the cold comes into the room.

My wife and I have a room that faces west so we get a lot of warmth buildup in our room during the later hours of the day. This coupled with our apartment complex's failure to properly size the central air's compressor to our square-footage means our room is hot and the AC can't do anything to cool it below 80F any time of the day (Texas Summers). After a month of hot nights we decided to get a portable unit and now that we've got this we won't ever go back.

###If you own this unit and the temperatures aren't reading properly, insulate the exhaust hose with some foil from where it connects to the unit and about 2 feet after that###

Benefits:

Remote controlled

Easy to install kit into window. Easy to move as well with the built-on castor wheels

Cools great our room is maybe 15 x 15 and we can keep it at 73 degrees all night without an issue. Unit goes to 61 degrees.

Fan noise is pleasant we like white noise

Thermostat shuts compressor off once temp is reached, kicks back on when temp rises again.

Timer is easy to set and helps to save energy.

Energy usage is a lot less than running the central air all night (My KilaWatt meter gave me an average of 5.92kWh per night over 5 days or roughly $9 a month)

Doubles as a dehumidifier with 45 pint capacity. Comes with hose for draining. Don't use the hose if just using it as an AC unit.

Pulls a lot of dust out of the air. Just make sure you clean your filters about once a month.

Downfalls:

Blue led-lit display on the front is too BRIGHT. We cut a flap of thin cardboard and taped it to the unit along the top and sides using some electrical tape. Doing so prevents remote from functioning with unit though.

Hose comes out at a 90 degree angle from the unit making it difficult to place next to a wall. Clearance required is roughly 1 foot behind the unit to allow proper air flow.

Hose coming out the rear tends to get hot and gives off ambient heat. Since the units thermostat is literally right above the hose (located under the top rear filter on the upper right) the temperature readings can be off by as much as 10 degrees. At first we were having issues with the compressor running all night non stop. When I figured out what was going on I insulated the hose with some foil where the hose connects to the unit and about 2 feet more of the hose from there. Temps now read properly.

We bought our unit from Best Buy with my wife's employee discount so we paid quite a bit less than what Amazon is selling it for but I would have gladly paid the amount here for the pleasant sleep we now both enjoy.

I bought this Danby portable air conditioner for my bedroom, since in the summer, I turn my central air conditioning system upto 82 degrees at night, but keep my bedroom at 74. The room is about 175 square feet, and I must say, this air conditioner is absolutely awesome! The fan setting on the low speed is probably one of the quietest fans i've ever heard in a portable, and, as a guy who has studdied, and know quite a bit about air conditioning, let me just say, this 8000 BTU unit is well designed, and, even when the condenser fan kicks in, even that fan is not noisy at all. I've had sever different portable units over the past few years, and, if you're looking for a unit to cool either maybe your home office, maybe a den, or bedroom, trust me! with this, you can't go wrong. Danby is one of the only portable units that, besides a drain plug at the bottom, you may also hook up a standard garden hose, via the hose connector which is on the back of the machine, I do this, with the unit emptying into a 5 gallon water bottle, or you could hook the hose upto a condensate pump, and never have to worry about that rubber drain plug which like most portable air conditioners, is at the bottom of the unit, and can be a royal pain in the rear to get to, especially if the bucket fills to capacity. The remote control is quite small, but works like a champ, and has a little cut-out on the air conditioner to keep it when not in use. When you remove the remote from the storage compartment, there 4 buttons, your temp up and down, the mode button, and your fan speed button. The timer defaults at 8 ours, and must be set with the remote, but I _love this remote, both the small size in your hand, and the ease of how it interacts with the air conditioner flawlessly. With all of this said, I urge you to check this unit out, but, make sure, please! size your room first! I hear so many people come to me and say that a certain portable air conditioner doesn't work, then they tell me, well? my room is 3 or400 square feet. If you don't size properly, then my friend, you will be bitterly disappointed in the the units inadequate performance. Thanks for reading, and good luck in buying your air conditioner for the coming summer ahead.

Dont know what others have been disappointed in but I bought this to cool a two car garage that we made rec room. It took the temp from 80 to 74 in less then 40 minutes. Runs about as loud as others. Add a fan in the room too and we are more than pleased.

Honest reviews on Danby DPAC8KDB Portable Air Conditioner

This A.C is a pretty good one, except it doesn't have the power to cool down a large lving room, but it perfectly cools down a small room. The only thing is that it uses too much power, epecially in old buildings. I would recommend this A.C for a small room, but not for a large living room. You should also plug it alone, so there is lss chance it turns off the power.

I put it on a table next to the window and connected a 6 inch diameter pipe for good air flow to the intake by making a scoop out of card board and duct tape then ran the pipe out the window making it a dual hose system.I kept the intake and exhaust hoses as short and straight as possible. It works much better now, it was almost useless before.
